I would like to set the tappets sound like a diesel motor


Depending on the engine will determine if you can "adjust the tappets". Older cars had solid lifters so they had to be adjusted. Newer cars have hydraulic lifters and need no adjusting.

If your tappets sound like a "diesel motor" it may be they are not getting oil - or the center of the tube that provides oil to the tappets are blocked.

Need to remove the valve cover and run the engine just long enough to see if oil is coming out of the lifter. If when you remove the valve cover and the lifters look dry then you have a "lubricating problem" and you need to get it taken care of immediately.

I need the engine valve spec for a 1984 chevy 6.2 diesel. We are adjusting the valves.


VALVE ADJUSTMENTS All gasoline and diesel engines in this guide use hydraulic valve lifters, which require no periodic maintenance or adjustment. However, in the event of cylinder head removal or any operation that requires disturbing or removing the rocker arms, the rocker arms must be adjusted in order to position the pushrods to allow the hydraulic lifters to maintain zero lash. Refer to the valve lash adjustment procedure under Rocker Arms, earlier in this Section.

Is there a diagram for the cylinder heads of a 1991 5.7 liter engine, especially the valve components? Thank you, Dan


Hydraulic Lifters REMOVAL & INSTALLATION 4.8L Engines
  1. Remove the rocker cover.
  2. Remove the engine side cover.
  3. Back off the rocker arm adjusting nuts and remove the pushrods. Keep them in order for installation.
  4. Reaching through the side cover opening, lift out the hydraulic lifters. If your are going to re-use the lifters, remove them one at a time and mark each one for installation. They must be re-installed in the same locations. If a lifter is stuck, it can be removed with a grasping-type lifter tool, available form most auto parts stores.
  5. Inspect each lifter thoroughly. If any of them shows any signs of wear, heat bluing or damage, replace the whole set. To install:
  6. Install and coat each lifter with engine oil supplement.
  7. Install the remaining components by reversing the removal procedure.
  8. Once installation is complete, adjust the valves as described in the valve lash procedure. Fig. 1: Stuck lifters must be freed using a slide hammer type lifter removal tool tccs3813.jpg
4.3L, 5.0L, 5.7L And 7.4L Engines
  1. Remove the cylinder head cover.
  2. Remove the intake manifold.
  3. Back off the rocker arm adjusting nuts and remove the pushrods. Keep them in order for installation.
  4. Remove the lifter retainer bolts, retainer and restrictor.
  5. Remove the lifters. If your are going to re-use the lifters, remove them one at a time and mark each one for installation. They must be re-installed in the same locations. If a lifter is stuck, it can be removed with a grasping-type lifter tool, available from most auto parts stores.
  6. Inspect each lifter thoroughly. If any of them shows any signs of wear, heat bluing or damage, replace the whole set.
  7. Coat each lifter with engine oil supplement prior to installation. Tighten the retainer bolts to 12 ft. lbs. (16 Nm). Adjust the valves as described in the valve lash procedure.
6.2L And 6.5L Diesel Engines Fig. 2: Diesel engine valve lifter 84903155.gif
  1. Remove the cylinder head cover.
  2. Remove the rocker arm shaft, rocker arms and pushrods. Keep all parts in order and properly identified for installation.
  3. Remove the clamps and lifter guide plates.
  4. Remove the lifters by reaching through the access holes in the cylinder head with a magnetic lifter tool. If you are going to re-use the lifters, remove them one at a time and mark each one for installation. They must be re-installed in the same locations. If a lifter is stuck, it can be removed with a grasping-type lifter tool, available form most auto parts stores. To install:
  5. Inspect each lifter thoroughly. If any of them shows any signs of wear, heat bluing or damage, replace the whole set. NOTE: Some engines will have both standard and 0.010 in. (.0039mm) oversize lifters. The oversized lifters will have "10'' etched into the side. The block will be stamped "OS'' on the cast pad next to the lifter bore. and on the top rail of the crankcase above the lifter bore. WARNING
    New lifters must be primed before installation. Damage to the lifters and engine will result if new lifters are installed dry!
  6. Prime new lifters by immersing them in clean kerosene, engine oil or diesel fuel and working the lifter plunger while the unit is submerged.
  7. Prior to installation, coat the lifter roller with engine oil supplement. Re-used lifters must be installed in their original positions!
  8. Install the lifters.
  9. Install the guide plates and clamps. Tighten the clamp bolts to 18 ft. lbs. (26 Nm).
  10. After all the clamps are installed, turn the crankshaft by hand, 2 full turns (720°) to ensure free movement of the lifters in the guide plates. If the crankshaft won't turn, one or more lifters may be jamming in the guide plates.
  11. The remainder of assembly the reverse of disassembly.

I have a 1995 Chevy 2500 6.5 turbo diesel and the blow. So I was wondering if theirs any gas engines that will bolt in its place? thanks D Hawkins


Any smallblock chevy to a bigblock chevy will bolt up. examples I would go with : 350 or a 454 . The 6.5 uses the same transmission bolt pattern as these engines. If it's an automatic the flywhell might still work on the 350 or 454.

My 99 chevy malibu Clean out lifters


add a litre of diesel and a 3 sec squirt of fairy washing up liquid ,use vehicle for a week and see how it sounds ,if its quietened down a bit ,change the oil and use a cheap diesel engine oil and then add some more diesel and fairy and leave another week ,if it still hasnt quiented down then strip and repair ,is has quietened down the change oil again for good measure and use the diesel engine oil as its a detergent oil and then change oil at approx 6000mile interval no longer and use the cheap oil .Change oil filter every third oil change and you will not get a repeat of the problem.Use an expensive long life oil and the problem will re appear ,because the additives and combustion residues will clog up and stick the hydraulic valve lifters

I just replaced all of my hydraulic lifters and no compression!


Yes, you've overtightened the lifters causing the valves to not close completely. If you did not prime the new lifters before you installed them and tightened them with the engine off they are most likely collapsed. back off all of the rockers to just snug and make sure the engine is running when you readjust them. Usually you need to let new lifters sit in a can of oil for a while to fill up. I've used a syringe to fill lifters prior to installation. Did you replace the push-rods also? If so were they the same length as the originals?
